The architecture also comprises one or more user devices 108 ₁, 108 ₂, . . . 108 _(n) (collectively referred to as user devices 108) and a database 112 connected to the estimation computing device 100. As shown in the FIG. 1, such user devices 108 are communicatively coupled to the estimation computing device 100 through a network 110 for receiving input data.

The user devices 108 comprise an application program that uses the services of the estimation computing device 100. The user devices 108 with the application program may be implemented in a variety of computing systems, such as a laptop computer, a desktop computer, a notebook, a workstation, a mainframe computer, a server, a network server, and the like. The user devices 108 may be used by various stakeholders or end users of the organization, such as project managers, executives and employees

In an embodiment, the user devices 108 are used by associated users to provide input data regarding requirements of server virtualization. The user devices 208 are installed with interface 106 for communicating with the estimation computing device 100 over the network 110.

In one implementation, the estimation computing device 100, as shown in FIG. 1, includes a central processing unit (“CPU” or “processor”) 102, a memory 104 and an interface 106. The processor 102 may comprise at least one data processor for executing program components and for executing user- or system-generated requests. A user may include a person, a person using a device such as those included in this invention, or such a device itself. The processor 102 is configured to fetch and execute computer-readable instructions stored in the memory 104. In one implementation, the memory 104 is communicatively coupled to the processor 102. The memory 104 stores processor-executable instructions to estimate optimal resources for server virtualization. The estimation computing device 100 may include the input/output (I/O) interface 106 for communicating with the one or more user devices 108.

In an implementation, the estimation computing device 100 also acts as user device. Therefore, the input data are directly received at the estimation computing device 100 to estimate optimal resources for server virtualization.

The database 112 stores information relating to the estimate optimal resources for server virtualization.

FIG. 2 shows detailed block diagram of estimation computing device 100 in accordance with some embodiments of the present invention.

In one implementation, the estimation computing device 100 may be implemented in a variety of computing systems, such as a laptop computer, a desktop computer, a notebook, a workstation, a mainframe computer, a server, a network server, and the like

In an embodiment, one or more data 202 may be stored within the memory 104. The one or more data 202 may include, for example, input data 206, filtering rules 208, field mapping rules 210, other data 212.

In an embodiment, the input data 206 comprises input received from user regarding current setup of IT infrastructure of an entity. The input comprises asset information, type of workload, breakup of each data center location, application information, hardware specification and architectural consideration. In an exemplary embodiment, the input data may be stored in database 112. The user may update and/or modify the input data 206. As an example, the input data 206 may be provided by the user in a document format selected from at least one of .csv, .xls etc.

The filtering rules 208 comprise one or more rules to filter the input data 204. The filtering rules 208 filters out the input data 206 which are not required to estimate the resources for server virtualization. The result of applying filtering rules 208 is filtered input data which is then processed further for estimation of resources for server virtualization. Few non-limiting examples of filtering rules may be filtering out the servers which are legacy in nature, operating system which are not considered for consolidation, locations which are not in scope for the transformation plan. A person skilled in the art would understand that other filtering rules based on the requirement may be used with the present disclosure.

The field mapping rules 210 is used to perform field-column mapping of the input data 206. The field mapping rules 210 maps the fields in the input data with a respective column, for example a column of excel sheet as illustrated in FIG. 5.

In an embodiment, the data 202 in the memory 104 is processed by the modules 204 of the processor 102. The modules 204 may be stored within the memory 104.

In one implementation, the modules may include, for example, an input module 214, an analysis module 216, a processing engine 218, a transformation engine 220, a learning module 222. The estimation computing device 100 may also comprise other modules 224 to perform various miscellaneous functionalities of the computing device 100. It will be appreciated that such aforementioned modules may be represented as a single module or a combination of different modules.

In an embodiment, the input module 214 receives input data 206 from the one or more user devices 108 associated with the user. The input module 124 receives inputs from the user regarding the requirements of server virtualization. The input data 206 received by the input module 214 is stored in the database 112.

The analysis module 216 retrieves the input data 206 from the database 112. The analysis module 216 then categorizes the input data 206 into one or more predefined categories like data center locations, assets make and model, host ids, production vs non-production environment, critical vs medium critical applications, operating systems information and database version details etc. In an embodiment, the one or more categories are predefined based on the type of sizing user wants to perform. These categorized data input is then updated into the database 112.

The processing engine 128 processes the input data 206 to estimate optimal resources for server virtualization. The processing engine 218 comprises one or more sub modules as illustrated in FIG. 3A. The sub modules of the processing engine 218 comprise a filtering module 302 and a virtualization module 204.

The filtering module 302 filters out data which are not required to design IT landscape information of the set of target servers. The result from the filtering module 302 is the data which is used for further processing for estimating optimal resources for server virtualization. As an example, the filtering module 302 filters out data like applications which are legacy in nature, operating system which are not considered for consolidation, locations which are not in scope for the transformation plan etc. Further, the filtering module 302 performs data sensitization on the filtered input data. The data sensitization comprises aligning the filtered input data into a predefined format.

Further, the filtering module 302 performs field-column mapping of the input data using the field mapping rules 208 in the database 112. While performing field mapping, the user has the option to define default values for the columns for which data are not provided by the user. An exemplary screenshot of the field column mapping is illustrated in FIG. 5. For example, user does not provide data for server's core column. In such case, the user can define default value for this server column like 4. These values get stored into the utility as default value for this core column throughout project life cycle for sizing calculations. After the field mapping, the sensitized data is sent to the virtualization module 304.

The virtualization module 304 generates current IT landscape information of a set of servers using the filtered input data. In an embodiment, the virtualization module 304 determines number of servers which are virtualized, current server virtualization ratio, current utilization levels, existing physical vs. virtual servers, number of core and Random Access Memory (RAM) etc. Also, the virtualization module 304 determines values of virtualization parameters for a set of target servers using the current IT landscape information and predefined rules.

Referring back to FIG. 2, the transformation engine 220 transforms the current IT landscape of set of servers to IT landscape of set of target servers. The transformation engine comprises one or more sub modules as illustrated in FIG. 3B. The one or more sub modules comprise a transformation module 306 and reports module 308.

The transformation module 306 generates the complete transformation snapshot which drives the target transformation blue-print design for server virtualization. Further, the transformation engine 306 determines IT landscape information of set of target servers using the current IT landscape information and the values of virtualization parameters.

The reports module 308 provides 360 degree overview about the information of IT landscape information of set of target servers. In an embodiment, the reports module 308 generates one or more reports indicating the estimated optimal resources for server virtualization. The report can be generated in one or more predefined formats include, but are not limited to, .ppt, .xls, .doc, .pdf.

Referring back to FIG. 2, the learning module 222 is an intelligent repository which captures the similar set of incidents and activities for each of the individual projects which are performed by user. The learning module 222 also collects the feedback of user about the quality of inputs which are used in enhancing the future recommendations of the system.

FIG. 4 shows a flowchart illustrating a method for estimating optimal resources for server virtualization in accordance with some embodiments of the present disclosure.

As illustrated in FIG. 4, the method 400 comprises one or more blocks for estimating optimal resources for server virtualization by the estimation computing device 100. The method 400 may be described in the general context of computer executable instructions. Generally, computer executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform particular functions or implement particular abstract data types.

The order in which the method 400 is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the spirit and scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.

At block 410, receive, by the estimation computing device, input data relating to requirements of server virtualization from a user device. The input module 214 receives the input data provided by the user in the form of import file for e.g. .csv, .xls etc. In an embodiment, multiple files can be received from the user which contains Configuration Management Database (CMDB) information of the user in a very raw fashion. The input data is then consolidated in a predefined format to standardize and sensitize the inputted data. The input data is then forwarded to the filtering module 302.

At block 420, filter, by the estimation computing device, the input data by applying filtering rules. An exemplary snapshot of filtering the input data is illustrated in FIG. 6. In an embodiment, the input data is filtered by applying the filtering rules 208 to eliminate unwanted data. The result of data filtration is filtered input data which is used for further processing. The one or more filtering rules 208 include, but are not limited to, type of Operating System (OS) like Unix, Mac, type of applications like legacy or vertical specific, type of server like virtual servers and location of servers like remote offices etc. A person skilled in the art would understand that any other filtering rules may be used with the method of present disclosure. As an exemplary scenario, UNIX environment is not considered for virtualization because of the application dependency and the high workloads. Also, servers which are already virtualized are not considered as candidate for server virtualization. Another criteria for elimination is criticality of the servers and the environment type, for example production/non production/test. The production servers are eliminated from virtual candidates list as the workloads will be higher and the application requires low latency.

At block 430, generate, by the estimation computing device, current IT landscape information of a set of servers using the filtered input data. To determine the current IT landscape information of the set of servers the filtered input data is sensitized to convert the input data into a predefined format. In an embodiment, the filtered input data is aligned in a predefined format. Further, field column mapping of the data is done using the field mapping rules 210. While performing field mapping the user has the option to define default values for the columns for which data are not provided by the user. For example user does not provide data for core column of a server. In such case, the user can define default value for this server column like 4, as illustrated in FIG. 5. The default values are stored into the database 112 as default value for this core column throughout project life cycle for sizing calculations. Then, the current IT landscape information of a set of servers is determined using the filtered and sensitized input data.

At block 440, determine, by the estimation computing device, values of virtualization parameters for a set of target servers using the current IT landscape information and predefined rules. In an embodiment, using the current IT landscape information and the predefined rules available in the database 112, the values for the virtualization parameters for set of target servers sizing are determined. The current IT landscape information and the predefined rules are categorized into appropriate categories including, but not limited to, core, Random Access Memory (RAM), location breakup, application workload segregation, systems make and model, current virtualization ratio etc. The categorization depends on the parameters defined by the user to draw the transformation snapshot for the target IT landscape of the organization. In an embodiment, if any information relating to the defined parameter is found missing or is incomplete, then the information is automatically populated based on the analyzed patterns generated by the rules in the database. FIG. 7 depicts an exemplary screenshot of categorization of input data received from the users to determine target virtualization candidates.

At block 450, determine, by the estimation computing device, IT landscape information of the set of target servers using the current IT landscape information and the values of virtualization parameters for estimating optimal resources for server virtualization. In an embodiment, the IT landscape information of the set of target servers is determined based on the one or more parameters. One of the one or more parameter may be total number of core, RAM and server utilization levels in the current IT landscape of the enterprise. Another parameter may be the target consolidation plan and server utilization levels required for target servers for each of the applications workload. For example, if an enterprise has 100 dedicated physical servers with 10 core each and with the maximum utilization level of 30%, i.e ((=100*10)*30%) that indicates 300 cores are used by the enterprise and 700 core are not utilized. Then, the workload is identified based on the application performance behavior patterns which can be accommodate onto these servers to increase the utilization levels and determine Return on Investment (ROI) for the user.

In another example, where workloads need to move to new hardware/server, multiple mix and match of servers product portfolio stored in the database is considered. In an embodiment, the user can choose the type of servers based on the Original Equipment Manufacturer (OEM) product, make and model, server configurations etc. to design the target server estate.

In an embodiment, the method further comprises performing ROI calculation which is used to determine saving of the user on the hardware. The ROI calculation primarily determines the user's Capital Expenditures (CAPEX) and Operating Expense (OPEX) investments, power and rack space requirements in the data center, software licenses cost which will be associated to the new implementation design for the user, savings of the user owing the new transformed estates etc. FIG. 8 depicts an example of the ROI report generated for the user.

In an embodiment, the method comprises capturing the estimated output, analysing the different outcomes and updating the rules in the database 112 automatically on the frequent basis. The set of parameters considered for self-learning and updating the rules are based on the sizing history and patterns based on the different scenarios. As an example, the different scenarios include most used sizing patterns, OEM/product specific patterns, patterns mostly used for the specific geographies, patterns mostly used for the specific vertical/industry, patterns mostly used for the specific type of workload, update new servers list (launched by OEM), update End-Of-Life/End Of Sale (EOL/EOSL) for particular server from OEM, update best practices for server sizing, server update notifications, user feedbacks, patterns used for winning themes etc.
